Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00036 | $0.00447 |
| Opus 5 | $0.00018 | $0.00224 |
| Sonnet 5 | $0.00007 | $0.00089 |
| Haiku 4.5 | $0.00004 | $0.00045 |
Grade A, and why
api-authorization-and-bola scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to api-authorization-and-bola — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
SKILL: API Authorization and BOLA — Object Access, Function Access, and Mass Assignment
AI LOAD INSTRUCTION: Use this skill when an API exposes object IDs, nested resources, or role-sensitive functions and you need a focused authorization test path: BOLA, BFLA, method abuse, and hidden field control.
1. CORE TEST LOOP
- Create Account A and Account B.
- As Account A, capture create, read, update, and delete flows.
- Replay with Account B's token.
- Test sibling endpoints, nested endpoints, and alternate HTTP verbs.
2. TEST SURFACES
| Surface | Example |
|---|---|
| object read | /api/v1/orders/123 |
| nested object | /api/v1/users/1/invoices/9 |
| admin or internal function | /api/v1/admin/users |
| update path | PUT, PATCH, DELETE variants |
| hidden JSON fields | role, org, verified, tier |
3. QUICK PAYLOADS
{"role":"admin"}
{"isAdmin":true}
{"org":"target-company"}
{"verified":true}
4. WHAT TESTERS MISS
- object IDs in headers, cookies, GraphQL args, and nested objects
- alternate methods sharing the same route but weaker authz
- parent check present, child resource check missing
- admin docs revealing extra writable fields
5. NEXT ROUTING
- For JWT or token-layer abuse: api auth and jwt abuse
- For GraphQL and hidden parameter discovery: graphql and hidden parameters
- For broader IDOR patterns outside APIs: idor broken object authorization
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

api-authorization-and-bola is a skill published in the GitHub repository ShulkwiSEC/bb-huge (22 stars, last pushed 1mo ago), licensed MIT. It adds 36 tokens to every session and 447 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to api-authorization-and-bola, differing in 0 lines, and is treated as a copy.
